what is the slope of the line that passes through the points (-10,9) and (-10,18)? write your answer in simplest form.
Answer
Explanation:
Step1: Recall slope - formula
The slope formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1=-10,y_1 = 9,x_2=-10,y_2 = 18$.
Step2: Substitute values into formula
$m=\frac{18 - 9}{-10-(-10)}=\frac{9}{-10 + 10}=\frac{9}{0}$. Since division by zero is undefined, the slope of the line is undefined.
Answer:
Undefined
